[I want to find their school and see what it's like,] Bell decides, and she starts reading passerby forearms to seek someone who's headed in that direction. It's almost like they're trying to be convenient for invisible spies.
The school appears to operate in shifts - they're underground, and people can sleep as well during the day as they can at night, so it's most efficient that way. They get to the school just as First Shift is taking over from Third Shift, and watch the history teacher they followed setting up for the day and greeting her students. The lesson is spare, factual, and delivered to relatively attentive children.
[The place is a match for its president,] Sherlock comments. [Very unfrivolous.]
[Very. I wonder what they'll do in sudden excess. I think my hometown would throw a party. I'm not sure these people know what a party is.]
[I am really very tempted to wish each and every one of them a cornucopia and an instruction packet, just to see what happens.]
[I don't think they're underfed - just - careful. But let's have a look at the dining hall.] It's easy to find someone on their way to the dining hall after they leave the school. Everyone lines up and gets a reasonable portion of food for their size. [Yeah. I mean, if something happened to their supply they'd be in trouble, but I don't think cornucopias are the key to sweeping cultural change, especially not since we know they take refugees when refugees get this far.]
[This would be a very dramatic time to appear,] observes Bell.
She waits just a moment longer, and then Coin says: "So as far as you know, Nine is no readier to rise up than it was the last time we heard news from that part of the country?"
"Far as I know," says one of the refugees, "nobody anywhere's ready for that."
And Bell appears, and says, "You haven't been looking hard enough."
Everyone besides them in the room is taken aback, but Coin recovers fastest - she hits a button for security, and Bell says, "Hey, I'm not hostile. There's no call for that."
"Who are you, then?" says Coin in a low, dangerous voice.
"I," says Bell, and her sentence is broken up by the fact that she teleports across the room to avoid the quick-responding security guards, "am just a girl" teleport "from Four" teleport "who is very ready" teleport "to - look, this is very annoying" teleport "can you call them off?" teleport "ready to attack the Capitol." (Teleport. Teleport.)
[Would you like me to do something about those?]
"Stand down," Coin says, after it becomes blindingly obvious that her guards are not going to catch Bell. "How are you doing that?"
"Magic -" At the look on Coin's face, Bell shakes her head. "No, literally, magic, I'm not mocking you. I got it from another world."
[Have we anything flashier to demonstrate with?] she wonders. [I'm not sure what would make the best impression.]
"Magic," says Coin flatly. "From another world."
"Yes, exactly, I'm glad our accents have turned out to be mutually intelligible. I'm Shell Bell."
"I am President Coin."
"It says so on the door to your office," Bell points out. "Tell me, what's your plan for a District or several who do want to overthrow the Capitol?"
"Total war," says Coin shortly.
"Classified," says Coin shortly.
"Look," says Bell, "since you're in the middle of a meeting, maybe I should go and we should schedule something and you can write it on your arm and I won't be interrupting. Does that sound good?"
"I believe I can rearrange my schedule for this," says Coin, and she shoos the refugees and their helpers out the door. (The security stays.)
"Very much so," replies Coin. "How did you get to this 'other world'?"
"Walked there," says Bell. "Or maybe I should just say 'classified'; is that politer?"
There is a silence, and then Coin says, "You look familiar."
"Tribute from Four, a couple years back," says Bell easily. "A Career took my place. That was after I found the other world but before I extracted much magic from it."
